Research On Scenario-Based Reliability Testing Of Component-Based Software

In recent years, software has becoming more and more complex and large-scale. The software development approach named Component-Based Development has been the trend in software development. How to assure the quality of component-based software, especially the reliability of software, has become one of the most important things in software engineering. Although many researches have been done to improve the quality of software, there are many issues and challenges in testing component-based software.We analyse and compare the existing scenario-based testing technologies, give the formal definition of UML sequence diagram, define a sequence-based scenario model, and propose a scenario-based testing framework for the testing of component-based software. Based on the scenario model and the testing framework we design and implement an automatic testing tool. The tool sets up the usage model based on scenarios, intercepts the interaction information of component-based software by using aspect-oriented technology, and generates the random number by a random number generator to simulate the method.This research facilitates the quality assurance of component-based software, improves user's confidences in software quality, and simplifies the complexity of testing.
